IRVINE, CA—Those who follow @GlobeStcom on Twitter and @GlobeStLIVE may have seen a post teasing the announcement, but GlobeSt.com has learned that John Hancock, the US division of life-insurance company Manulife Financial Corp., has acquired Oracle Tower, a 12-story, 272,887-square-foot, class-A office tower at 17901 Von Karman Ave. within the Irvine Concourse Corporate Center here. The purchase price was not disclosed.

GlobeSt.com was unable to reach John Hancock before deadline to discuss the seller's identity or the purchase price, but the property is listed and shown on LBA Realty's website. We will update this story as more information becomes available.

Oracle Tower, constructed in 1985, is a LEED Gold-certified building that was renovated in 2000 and 2010, modernizing the interior, building systems and exterior public spaces. Its location at Von Karman Ave. and Main St. here is adjacent to the 405 freeway and within the 3-million-square-foot Irvine Concourse, offering access to an array of amenities.

Operating as John Hancock Real Estate in the US and Manulife Real Estate in all other parts of the world, the company's real estate portfolio is diversified by both geography and asset type, consisting primarily of prime office and industrial properties as well as select retail and multifamily residential properties, in key metropolitan centers throughout Canada, Asia and the US. With this new acquisition, the company's global real estate portfolio now represents a market value of $10.5 billion, with properties totaling more than 39 million square feet. Other key markets for the firm in the US include Boston, New York, Los Angeles, San Francisco, Atlanta and Washington, DC.

According to Kevin Adolphe, president and CEO of Manulife Real Estate, “This latest acquisition is consistent with our strategy to seek out complementary assets in the key gateway markets in which we do business. Oracle Tower is a fantastic addition to our portfolio. It is a core asset that provides long-term value that strengthens our commitment in the Greater Los Angeles area.”

The acquisition is just one of the office trades that have taken place recently in Irvine. As GlobeSt.com reported earlier this month, San Francisco-based Swift Real Estate Partners has acquired an office building at 111 Pacifica, a 67,496-square-foot institutional-quality property here, from Kilroy Realty for an unspecified amount. The building will house Swift's Southern California office, where industry veteran Malcolm O'Donnell, who just joined the firm as partner, will be based.
